Abstract:

Lupus myocarditis (LM) is characterized by complex myocardial autoimmune processes leading to inflammation,cardiomyocyte injury and reparative fibrosis.Clinical recognition of lupus myocarditis is challenging due to a paucity of classic cardiac symptoms.There is a lack of a reliable noninvasive diagnostic test.Cardiac magnetic resonance imaging (CMR) is a diagnostic tool for the assessment of patients with suspected lupus myocarditisCMR has the advantages of nontraumatic,nonradioactive,no iodine contrast agent,high repeatability.T1 and T2Mapping are new quantitative imaging techniques,which are sensitive techniques for identifying myocarditis,edema and fibrosis.CMR has important value for early diagnosis,risk assessment,guiding treatment strategy and prognostic evaluation of LM.

Key words: lupus myocarditis, cardiac magnetic resonance, late gadolinium enhancement
